BACKGROUND ART

In recent years, wine has been remarkably popularized, and brands,producing areas, kinds, tastes, and the like of wine are diversified.This trend has been promoting the opening of bars specializing in wine,which are so-called wine bars, and they are offering various kinds ofwines that meet the tastes of customers. In this case, trying wines of alarge number of brands is necessary and in addition, there are demandsfor selling by measure such as so-called glass wine, and therefore, itis necessary to open a large number of bottles. However, since air ismixed into wine once bottles are opened, the deterioration of wine isinevitable. This leads to such a situation that opening of a bottle ishesitated or unconsumed wine left in a bottle is wasted due to bottleopening.

As a means for avoiding such inconvenience, a liquid preserving devicestructured as described below has been proposed (refer to PatentDocument 1). This device includes: a pressure-reducing stopper which hasa fluid passage communicating the inside of a container with the outsidethereof and a down-flow valve for restricting the flow of a fluid in adirection of the inside of the container via the fluid passage and whichis able to install detachably on an opening portion of the container forcontaining liquid; a pressure-feed stopper which has a fluid passagecommunicating the inside of the container with the outside thereof and adown-flow valve for restricting the flow of fluid in a direction of theoutside of the container via the fluid passage and which is able toinstall detachably on the opening portion of the container forcontaining liquid; a connecting portion having a fluid passageconnectable to the fluid passage of the pressure-reducing stopper or thepressure-feed stopper in an airtight state; a pressure-reducing meansfor discharging air from the inside of the container to the outside ofthe container via the fluid passage of the pressure-reducing stopper orthe pressure-feed stopper; and a pressure-feed means for supplyingcarbon dioxide gas into the container via the fluid passages of thepressure-reducing stopper and the connecting portion.

Further, the applicant of this application previously proposed a wineextracting device so structured that the wine extracting device isattached to an opening portion of a bottle with the bottle placed upsidedown, and the bottle is opened while insoluble inert gas is beingsupplied, so that only a necessary amount of wine can be then extractedby the pressure of this gas (refer to Patent Document 2).

DISCLOSURE OF THE INVENTION

However, the liquid preserving device in the Patent Document 1 of theprior art is a large-scaled device and expensive, and therefore, it isnot suitable for use anytime and anywhere. Moreover, even whenonce-opened bottle is filled in a seal state with an oxidationpreventive gas and closed, the progress of quality deterioration cannotbe thereafter avoided because air enters if the bottle is opened again.Therefore, it is not suitable for adoption for tasting sets, selling byweight, and so on offered at, for example, wine bars. Further, the wineextracting device of the Patent Document 2 according to the proposal bythe applicant of this application also has some problems to be solved.Specifically, there remain problems in this device: firstly, wine isextracted while an insoluble inert gas is being supplied, but atroublesome operation such as rotating a cut cork by 90° at the openingportion of the bottle is required; and secondly, the operation forattaching the extracting device to the bottle is complicated.

An object of the present invention is to provide a fluid extractingdevice for wine and so on that is capable of extracting a fixed amountof a fluid such as wine when necessary, only requires easy operation forthe extraction, and is usable for a long-term preservation, andmoreover, to provide a fluid extracting unit and a fluid extractingsystem capable of providing convenience in the display and service atwine bars and so on through the use of this fluid extracting device.

In the present invention, means of the present invention taken forsolving the aforesaid problems and the operations thereof are asfollows. Here, the fluid includes not only liquid such as wine andcarbonated water but also fluid in general such as lactic acid bacteriabeverage, fruit juice with pulp, and fluid high in fluid drag such asedible oil.

A fluid extracting device according to a first invention includes: adevice body having a fluid storage portion capable of storing a fluid inan airtight state; an extracting portion positioned under the devicebody and allowing the fluid in the fluid storage portion to flow downvia an extraction valve; a gas supply port through which a deteriorationpreventive gas is to be supplied into the fluid storage portion; a valvedriving portion for putting the extraction valve into operation; and anoperation mechanism capable of operating the valve driving portion froman external part or the outside.

According to the fluid extracting device of the first invention, it ispossible to block air entering and extract only a predetermined amountof an arbitrary fluid such as wine or the like from the fluid storageportion anytime while supplying the deterioration preventive gas.Consequently, partial extraction of a fluid such as wine, for example,in a plurality of operations is made possible without deteriorating itsquality, which enables the extraction of a fixed amount of the fluidsuch as wine anytime when necessary and makes it possible to provide afluid extracting device for wine or the like that only requires an easyoperation for the extraction and is usable for long-term preservation.

A fluid extracting device according to a second invention is sostructured: that an upper portion of the fluid storage portion has amounting portion that is attachable to and detachable from a headportion of a bottle, which is placed upside down, in an airtight state;and that the mounting portion allows, when being attached to the headportion of the bottle, the fluid flowing down from the head portion ofthe bottle to flow down into the fluid storage portion in an airtightstate.

According to the fluid extracting device of the second invention, it ispossible to make a new supply of the fluid into the fluid storageportion from the bottle. Since the new supply of the fluid is conductedin the airtight state, the fluid never comes in contact with the airduring this period. Therefore, it is possible to extract a larger amountof the fluid than a fluid amount storable in the fluid storage portionand further to effectively prevent the deterioration of such a fluid.

A fluid extracting device according to a third invention is sostructured that the fluid flows down via a down-flow valve attached tothe head portion of the bottle.

According to the fluid extracting device of the third invention, anamount of the fluid flowing down to the fluid storage portion from thebottle can be adjusted by opening/closing the down-flow valve.

A fluid extracting device according to a fourth invention is sostructured: that the driving portion includes a first driving portionfor putting the down-flow valve into operation and a second drivingportion for putting the extraction valve into operation; and that theoperation mechanism is capable of operating the first driving portionand the second driving portion simultaneously or separately from theoutside.

According to the fluid extracting device of the fourth invention, thework of the operation mechanism makes it possible to operate thedown-flow valve and the extraction valve simultaneously or separately.Selection between the simultaneous operation and the separate operationof the first driving portion and the second driving portion may be madeas desired.

A fluid extracting device according to a fifth invention is sostructured that, when the operation mechanism is arranged to be capableof operating the first driving portion and the second driving portionsimultaneously, the second driving portion keeps the extraction valveclosed while the first driving portion is driving the down-flow valve toopen, and the down-flow valve is kept closed while the second drivingportion is driving the extraction valve to open.

According to the fluid extracting device of the fifth invention, thedown-flow valve and the extraction valve are never open simultaneously.Consequently, the fluid is not directly extracted to the outside fromthe bottle. If the direct extraction should be made, the air flowing ina reverse direction through the extraction valve could enter the insideof the bottle, but such a situation does not occur since the down-flowvalve is kept closed while the extraction valve is open and thedeterioration preventive gas is continuously supplied into the fluidstorage portion, so that there remains no room for the air to enter.

A fluid extracting device according to a sixth invention is sostructured: that the down-flow valve includes: a valve body having ahollow portion attachable to the head portion of the bottle; a dischargevalve capable of advancing and retreating in the hollow portion relativeto the valve body; a biasing member disposed in the hollow portion inorder to bias the discharge valve in a direction of the fluid storageportion; and an abutted portion having a down-flow hole that is closedwhen abutted on by the discharge valve biased in the hollow portion;that a recessed portion communicating with the hollow portion is formedin an end portion of the valve body in the direction of the fluidstorage portion; and that at least one streak of vertical groove isformed on an inner wall surrounding the hollow portion inside the hollowportion at least from the abutted portion.

According to the fluid extracting device of the sixth invention, owingto the inclusion of at least the above-described structure, it ispossible to effectively prevent the stagnation of the fluid flowing downfrom an outlet of the down-flow valve, namely, the down-flow hole of theabutted portion. Specifically, the fluid trying to flow down from thedown-flow hole sometimes stagnates at the down-flow hole and does notflow down due to its surface tension, which is thought to be caused byindividual or correlative influence by the size and shape of thedown-flow hole, viscosity of the fluid, pressure of the supplieddeterioration preventive gas, and so on. Though the specific-causalrelationship is not clear, it has been experimentally confirmed thatsuch stagnation can be prevented when the down-flow valve includes theabove-described structure.

A fluid extracting device according to a seventh invention is sostructured that the biasing member is a coil spring and a center axis ofthe coil spring is nonlinear. The nonlinear center axis causes thepressure given to the abutted portion via the discharge valve to beuneven in the periphery of the down-flow hole. This is thought to becontributing to the prevention of the fluid stagnation. The fluidextracting device according to the sixth invention can also prevent thefluid stagnation to some extent, but it has been experimentallyconfirmed that the co-use of the above-described coil spring can realizethe prevention of the fluid stagnation with higher reliability.

A fluid extracting device according to an eighth invention is sostructured that the extraction valve has a large-diameter rod portioncapable of closing a down-flow hole portion provided in a lower portionof the fluid storage portion.

According to the fluid extracting device of the eighth invention, it ispossible to constitute the valve with a small number of components,namely, the down-flow hole portion and the large-diameter rod portion.Owing to such a constitution, the opening/closing of the down-flow holeportion, in other words, the execution and termination of the fluidextraction can be conducted only by the descent and ascent of thelarge-diameter rod portion.

A fluid extracting device according to a ninth invention is sostructured: that a driving rod capable of moving upward and downward bythe operation of the operation mechanism is provided in the device body;and that an upper end portion of the driving rod is capable offunctioning as the first driving portion and a lower end portion of thedriving rod is capable of functioning as the second driving portion.

According to the fluid extracting device of the ninth invention, thedown-flow valve and the extraction valve can be opened/closed only bythe ascent and descent of the driving rod. The down-flow valve and theextraction valve are operated only by the driving rod, so that, when thedriving rod is moved upward to open the down-flow valve, the extractionvalve is closed, and on the other hand, when the driving rod is moveddownward, the down-flow valve is closed and the extraction valve isopened.

According to a fluid extracting device of a tenth invention, a rodbearing body is provided in an upper portion of the fluid storageportion. The rod bearing body includes an inner bearing supporting thedriving rod to be able to slide, an inside-diameter portion surroundingthe inner bearing, a down-flow passage for the fluid formed between theinner bearing and the inside-diameter portion, a gas supply passagecapable of supplying the deterioration preventive gas into the fluidstorage portion, and a ring-shaped projecting portion including a hollowportion communicating with the down-flow passage and projecting to sucha position that an end portion of the ring-shaped projecting portion iscapable of coming into contact with the fluid stored in the fluidstorage portion.

According to the fluid extracting device of the tenth invention, theinner bearing of the rod bearing body supports the driving rod to beable to slide, and the deterioration preventive gas is also suppliedinto the fluid storage portion via the gas supply passage. The fluidflows down via the down-flow passage and further passes through thehollow portion of the ring-shaped projecting portion communicating withthe down-flow passage to flow down into the fluid storage portion. Whenthe fluid flows down into the storage portion, the deteriorationpreventive gas of which amount corresponds to that of the flowed fluidflows in a revere direction through the down-flow passage from thehollow portion. When the storage level in the fluid storage portion israised due to the flow-down of the fluid from the bottle to reach thelower end of the ring-shaped projecting portion, an opening of thering-shaped projecting portion is closed by the stored fluid. Thisprevents the deterioration preventive gas from flowing into the hollowportion of the ring-shaped projecting portion, thereby stopping theflow-down of the fluid automatically. By appropriately determining aprojection amount of the ring-shaped projecting portion, a fluid amountto be stored in the fluid extracting portion can be set so as toconstantly become a predetermined amount. This eliminates the trouble ofoperating the operation arm under the monitoring of a flow-down amountof the fluid by an eye-observation of measurement calibrations or thelike of the fluid storage portion.

In a fluid extracting device according to an eleventh invention, an airvent valve for exhausting air inside the fluid storage portion isprovided. The air vent valve may be a manual one, but an automatic onethat automatically opens when the pressure reaches a predetermined valueand closes when the pressure reaches a predetermined value or lower ismore convenient.

According to the fluid extracting device of the eleventh invention, whenthe pressure inside the fluid storage portion reaches a predeterminedvalue or higher for some reason at the time of the supply of thedeterioration preventive gas, it is opened to cause the insidedeterioration preventive gas and so on to escape, so that the pressurecan be returned to a normal state. When the deterioration preventive gasis supplied, it is possible to exclude the air left in the fluid storageportion by opening the extraction valve, but it is also possible tosupply the deterioration preventive gas while the extraction valve iskept closed and exclude the air by the action of the air vent valve.

A fluid extracting device according to a twelfth invention is sostructured that the extracting portion includes: an outer cylinderconnectable to a lower portion of the fluid storage portion; an innercylinder fitted in an inner peripheral portion of the outer cylinder; aguide cylinder vertically extending in a range from the lower portion ofthe fluid storage portion to a position of a substantially centerportion of the extracting portion; a joint member fitted in a lowerinner peripheral portion of the guide cylinder to be connected to alower end portion of the driving rod; and an up and down movement membersupporting a lower end portion of the joint member and fitted to be ableto move upward and downward in a lower outer peripheral portion of theguide cylinder. Further, an extraction pipe is connected to a lowerportion of the joint member and the extraction pipe extends to aposition lower than a lower end portion of the extracting portion.

According to the fluid extracting device of the twelfth invention, whenthe driving rod and the extraction pipe which are integral with the upand down movement member via the joint member are moved upward anddownward, the fluid such as wine in the bottle is stored temporarily inthe fluid storage portion and further passes through the extractionpipe, so that the fluid can be poured to a glass or the like. Also inthis case, the continuous supply of the deterioration preventive gasblocks air entering, which prevents quality deterioration of the fluidsuch as wine.

A fluid extracting device according to a thirteenth invention proposes afluid extracting device for wine and so on so structured that theoperation mechanism includes: an operation arm provided to be able toswing on an outer side of the extracting portion; the up and downmovement member provided to be movable upward and downward in theextracting portion by the operation arm; and the joint member coupled tothe up and down movement member and the driving rod in an airtightstate.

According to the fluid extracting device of the thirteenth invention,the operation mechanism is constituted of the operation arm provided tobe able to swing outside the extracting portion, the up and downmovement member provided to be movable upward and downward in theextracting portion by the operation arm, and the joint member coupled inan airtight state to the driving rod vertically extending from the upand down movement member and the device body to the extracting portion.The extraction of the fluid in the bottle is conducted in such a mannerthat the driving rod is moved upward and downward under the airtightstate, and the down-flow valve for the bottle and the extraction valveare thereby opened/closed. The rise and fall operation of the operationmechanism allows the up and down movement member in the extractingportion to be able to move upward and downward by the vertical movementof the operation arm. The operation mechanism is structured to be ableto operate the driving rod inside the extracting portion from theoutside thereof while the airtight is maintained, and it makes itpossible to extract a predetermined amount of the fluid anytime whennecessary.

In a fluid extracting device according to a fourteenth invention, thefluid storage portion is constituted of a transparent material or atranslucent material. Since it is constituted of the transparentmaterial or the translucent material, the flow-down state of the fluidinto the fluid storage portion can be visually recognized. This enablesthe recognition of the existence or nonexistence of the fluid flow-downand an arbitrary increase/decrease of an extracted amount as required.

A fluid extracting device according to a fifteenth invention is sostructured that the head portion of the bottle and the mounting portionare connectable to each other via a coupling assist including a widering press-fitted to the head portion of the bottle and a coupling nutso formed that an inner peripheral portion thereof is capable of beingin close contact with the wide ring. The coupling assist enables theconnection between the head portion of the bottle and the device underthe state in which airtight is being maintained, and when they arecoupled to each other via the coupling portion, air entering is blockedby the wide ring. Further, since it is attachable and detachable only byrotating the coupling nut, it is easy to operate.

A fluid extracting device according to a sixteenth invention is a fluidextracting device for extracting a fluid from a bottle containing thefluid via a down-flow valve attached to a head portion of the bottlewhich is placed upside down, the device including: a device body havinga mounting portion attachable to and detachable from the head portion ofthe bottle in an airtight state and a fluid storage portion capable ofstoring the fluid flowing down via the down-flow valve in an airtightstate; an extracting portion positioned under the device body, forallowing the fluid in the fluid storage portion to flow down via anextraction valve; a gas supply port through which a deteriorationpreventive gas is to be supplied into a fluid down-flow passage betweenthe down-flow valve and the extraction valve; a first driving portionfor putting the down-flow valve into operation; a second driving portionfor putting the extraction valve into operation; and an operationmechanism capable of operating the first driving portion and the seconddriving portion simultaneously or separately from the outside.

According to the fluid extracting device of the sixteenth invention, anarbitrary fluid such as wine can be made to flow down to the fluidstorage portion from the bottle via the down-flow valve anytime whilethe air entering is being blocked and the deterioration preventive gasis being supplied, and moreover, only a predetermined amount can beextracted from the fluid storage portion. Consequently, it is possible,for example, to partially extract the fluid such as wine in a pluralityof operations without deteriorating its quality, so that a fixed amountof the fluid such as wine can be extracted anytime when necessary, andit is possible to provide a fluid extracting device for wine and so onthat requires only an easy operation for the extraction and is suitablefor a long-term preservation.

According to the fluid extracting device of the seventeenth invention,the down-flow valve and the extraction valve are never opensimultaneously. Consequently, the fluid is never directly extracted tothe outside from the bottle. If the direct extraction should be made,the air flowing in a reverse direction through the extraction valvecould enter the inside of the bottle, but such a situation does notoccur since the down-flow valve is kept closed while the extractionvalve is open and the deterioration preventive gas is continuouslysupplied into the fluid storage portion, so that there remains no roomfor the air to flow therein.

A fluid extracting method according to an eighteenth invention is afluid extracting method for extracting a fluid from a bottle via adown-flow valve attached to a head portion of the bottle containing thefluid, the method including: a first step of storing the fluid in theairtight storage body filled with a deterioration preventive gas byopening the down-flow valve to cause the fluid to flow down; and asecond step of discharging the fluid stored in the airtight storage bodyto the outside by opening an extraction valve included in the airtightstorage body.

The extracting method includes not only a fluidextracting method using the fluid extracting device according to thepresent invention but also includes a wide variety of fluid extractingmethods including the above-described steps. Any of the methods isexecuted under the state in which air entering that may cause thedeterioration of fluid quality is blocked, so that a fluid such as winecan be extracted anytime without causing any quality deterioration.Here, the airtight storage body represents a container storing, in anairtight state, the fluid flowing out of the bottle, and specifically,it also includes the above-described fluid storage portion.

A fluid extracting method according to a nineteenth invention ischaracterized in that the first step includes a step of exhausting airinside the airtight storage body and instead supplying the deteriorationpreventive gas. When no harmful gas such as air exists in the airtightstorage body and the inside of the airtight storage body is entirelyfilled with the deterioration preventive gas, the air exhausting stepmay be unnecessary, but otherwise, the air exhausting step is necessarysince the prevention of the fluid quality deterioration cannot beexpected unless the air is excluded.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention (hereinafter, referredto as “this embodiment” when appropriate) will be explained withreference to the drawings.

(Structure of Fluid Extracting Device Attached to Bottle of Wine or theLike)

First, as the structure of a fluid extracting device for oxidationprevention, the structure in which it is applied to a bottle of abeverage such as wine will be explained in this embodiment. A fluidextracting device 60 is attached to this beverage bottle, the fluidextracting device 60 being capable of extracting a beverage such as wineanytime from the bottle in which a down-flow valve is press-fitted inplace of an existing cork stopper, without deteriorating the quality.Further, a coupling assist 90 for coupling this fluid extracting device60 to the bottle in an airtight state is provided. The fluid extractingdevice 60 is capable of extracting wine or the like while preventingair, which deteriorates the quality of a fluid beverage such as wine,from entering the inside of the bottle.

FIGS. 1 and 3 show an external structure of the fluid extracting device60. This structure allows the fluid extracting device 60 to be attachedto a head portion B1 of a bottle B containing a fluid such as wine inthe airtight state via the coupling assist 90. As an example of thecoupling assist 90, adopted is the one constituted of the combination ofa coupling nut 91 that can be loosely fitted to the bottle head portionB1 and a wide ring 93 as a packing made of an elastic material that canbe press-fitted to the bottle head portion, as shown in FIG. 4. Thecoupling nut 91 can maintain internal and external airtight when a holeportion in a lower portion thereof comes in press contact with thepress-fitted wide ring 93. A female thread portion 91 a provided on anupper inner peripheral portion of this coupling nut 91 can bescrew-connected with a male thread portion 62 a provided on an outerperipheral portion of a mounting portion 63 of the fluid extractingdevice. When the female thread portion 91 a and the male thread portion62 a are thus screw-connected, the bottle B and the fluid extractingdevice 60 can be connected to each other under the airtight state.Incidentally, a ring cover 92 is attached to an outer peripheral portionof the coupling nut 91 of the coupling assist 90 in the drawing and thisis intended for the coupling nut to be easily operated.

As shown in FIGS. 1 and 3, main constituent elements of the fluidextracting device 60 in appearance are three elements, namely, a devicebody 61, an extracting portion 67 coupled to a lower portion of thedevice body 61, and an operation mechanism 70. The device body 61includes: a mounting portion 63 having a tubular portion 62 enabling thedevice to be attached to or received in the bottle head portion and abody portion 64 integrally formed with the cylinder portion 62; and afluid storage portion 65 coupled to a lower portion of the body portionand constituted of a container made of a transparent material. Further,a gas supply port 81 through which deterioration preventive gas is to besupplied into the device body 61 and an air vent valve 83 are providedin the body portion 64 (refer to FIGS. 1 and 4). The extracting portion67, which is coupled to the device body 61 at an upper portion thereof,includes an operation mechanism 70, and an extraction pipe 74 isprovided in a lower portion thereof O-rings 8 as airtight maintainingmeans are interposed at the connecting portions, thereby enabling theprevention of leakage of deterioration preventive gas supplied from thegas supply port 81. An operation arm 72 is attached as a constituentmember of the operation mechanism 70 at an intermediate position of theheight of the extracting portion 67, and the up and down movementoperation of this operation arm 72 enables a driving rod 75 constitutinga later-described driving portion provided inside and the extractionpipe 74 to be moved upward and downward. The driving rod 75 enables theextraction of a fluid such as wine in the bottle from the extractionpipe 74 by the up and down movement operation of the operation mechanism70.

Any kind of fluid can be a target of the extraction irrespective of thekind and property thereof, but here, wine is designated as a typicalbeverage, and gas mainly composed of nitrogen (hereinafter, referred toas “the N gas”) is adopted as deterioration preventive gas. The reasonwhy the N gas is adopted is that the gas is insoluble and inert to wine,which makes the gas suitable as gas for preventing quality deteriorationof wine by blocking the contact between air and wine after bottleopening or at the time of wine extraction. The N gas is supplied to thefluid extracting device 60 in such a manner that a gas supply device 85such as a gas bomb filled with the N gas is connected to the gas supplyport 81 via a gas supply hose 86.

(Method of Using Fluid Extracting Device)

In a method of using the fluid extracting device, the arrangement ofconditions under which the fluid in the bottle can be extracted isrealized through the following three steps of preparatory works. As afirst step, the existent cork stopper fitted in the bottle head portionB1 is pulled out in an atmosphere of deterioration preventive gas suchas the N gas, and instead, a down-flow valve 7 is press-fitted therein(refer to FIGS. 2(a) and 4). This means that the down-flow valve 7functions as a substitute stopper in place of the cork stopper. Thedown-flow valve 7 may be the one that has been mounted at a wineproducer before shipment. As a second step, the fluid extracting device60 is attached via the coupling assist 90 to the bottle head portion B1having the down-flow valve 7 press-fitted therein. As a third step, thebottle B having the fluid extracting device 60 attached thereto isplaced on a bottle setting table or the like (to be described later)installed at a wine bar or the like while the bottle is positionedupright or inclined at such an angle to allow the fluid to naturallyflow down, and it is set so that the extracting device is positioned ona lower side of the bottle. Then, the operation mechanism 70 of theextracting portion 67 is operated, which makes it possible to extract apredetermined amount of the fluid when necessary while preservingfreshness over a long period, under the state in which the qualitydeterioration of the fluid such as wine can be prevented by supplyingthe N gas into the fluid extracting device 60.

(Structure of Down-flow Valve)

The down-flow valve 7 used as a down-flow valve here will be explainedwith reference to FIGS. 2 a-2 c. This down-flow valve 7 is, as shown inthe drawings, a down-flow valve (plug with valve) having a dischargevalve 7 b in a body 7 a and the structure thereof is as follows. Themushroom-shaped discharge valve 7 b is inserted into an upper portion ofthe body 7 a constituted of a tubular member having a flange portion,and a cap 7 c is screwed to the upper portion for coverage, therebypreventing the valve from coming off. Further, an upper end portion of acompression spring 7 d as a biasing member abuts on a lower face portionon a rear side of a head portion of the discharge valve 7 b, so thatairtight can be maintained when the head portion of the valve receivinga biasing force of the spring is in close contact with a seat hole 7 iof the cap 7 c. A lower end portion of the compression spring 7 d issupported by a supporting member 7 e screwed into an insertion hole ofthe body 7 a. In passing, the strength of the biasing force of thespring 7 d is adjustable by rotating the spring supporting member 7 e tochange the position thereof.

As shown in the drawings, in the vicinity of an upper portion of thedown-flow valve 7, the body 7 a of plug with valve and the cap 7 c arescrew-fixed, and an O-ring 7 f as a packing is fitted to an upperportion of the flange portion to maintain airtight between the body 7 aand the cap 7 c. Rib portions 7 g, . . . are formed inside the vicinityof an upper end portion of the body 7 a at four places as shown in FIG.2 b, and the head portion of the discharge valve 7 b is movable upwardand downward in a state in which an outer peripheral portion thereof isin contact with these four rib portions. Therefore, when the headportion of the discharge valve 7 b is pressed against the biasing forceto be retreated, with an opening portion B2 of the bottle B facingdownward, the fluid such as wine in the bottle B passes through spaces 7s formed between these rib portions and through a gap formed between thehead portion and the seat hole 7 i of the cap 7 c, so that the fluid isallowed to flow out. In passing, since a portion lower than the flangeportion of the down-flow valve 7 is to be press-fitted into the openingportion B2 of the bottle B, the outside diameter of the portion is madesmaller than the diameter of the opening portion of the bottle by suchan amount that O-rings 7 k as seal members can be disposed between themin an elastic contact state.

By the way, since the inside diameter of the opening portion B2 of thebottle itself is diversified, it is difficult for the reason of cost tomake the down-flow valve adaptable to all the inside diameters.Therefore, in the present invention, a down-flow valve as shown in FIG.2 c is adopted, this down-flow valve being so structured that the outershape of the valve body is fixed and in place of the O-rings 7 k, sealmembers 107 k each constituted of a rubber ring having a T-shaped crosssection are attached to a plurality of places of the body 107 a. Theseal members 107 k are so structured that thick ring portions 107 r onthe inner side are fitted in grooves of the body 107 a and airtight canbe maintained by transformed portions 107 m in a flange shape which aremade by extending outer peripheral portions of the ring portions.Specifically, the seal members 107 k are so structured that the portions107 m in a thin flange shape are transformed to fill a gap between theinner periphery of the bottle B and the outer periphery of the valvebody 107 a when the down-flow valve 107 is press-fitted into the bottleopening B2, thereby enabling the adaptation to wide variety of bottlesizes. The adoption of such a down-flow valve can reduce the kinds ofplug sizes to be prepared, which can contribute to the reduction inrunning cost of wine bars or the like.

(Modification Example of Down-flow Valve)

Explanation will be given with reference to FIGS. 9 to 13. A down-flowvalve 111 includes a valve body 113, which has a hollow portion 112(refer to FIG. 13), attachable to the bottle head portion B1, adischarge valve 114 capable of advancing and retreating in the hollowportion 112 relatively to the valve body 113, a coil spring (biasingmember) 115 disposed in the hollow portion 112 to bias the dischargevalve 114 in a direction of the fluid storage portion 65, and an abuttedpiece 119 having a down-flow hole 117 which is closed when the dischargevalve 114 biased in the hollow portion 112 abuts thereon. The referencesymbol 113 p denotes a screw cap constituting a part of the valve body113. The screw cap 113 p is mainly intended for keeping the abuttedpiece 119 staying in the hollow portion 112 of the valve body 113.Ring-shaped elastic pleats 113 a for enhancing airtight to the bottleare formed on an outer periphery of the valve body 113. Further,ring-shaped lip portion 118 protruding in a depth direction of thehollow portion 112 is provided on a periphery of the down-flow hole 117.The lip portion 118 is provided because the lip portion 118, whenabutted on by the discharge valve 114, elastically transforms, therebyincreasing the closed state between them. Moreover, a recessed portion120 communicating with the hollow portion 112 is formed in an endportion of the valve body 113 in a direction of the fluid storageportion 65 (downward direction in FIG. 9), in other words, in an endportion of the screw cap 113 p. The highest effect was obtained when therecessed portion 120 is formed in a fan shape with the dimension thereofgradually becoming smaller from an outer periphery toward an innerperiphery of the end portion. Further, it is preferable to form at leastone streak of vertical groove 121, preferably plural streaks, on aninner wall 113 b surrounding the hollow portion 112 inside the hollowportion 112 from the abutted piece 119.

According to experiments conducted by the inventors, there are somecases when a fluid trying to flow down from the down-flow hole 117stagnates at the down-flow hole 117 (lip portion 118) due to its surfacetension and does not flow down, which is considered to be caused by theindividual or correlative influence by the size and shape of thedown-flow hole, viscosity of the fluid, pressure of the supplieddeterioration preventive gas, and so on. A wine bottle whose bottleopening has an inside diameter of about 13.5 to 15 mm was used in theexperiments, and the inside diameter of the down-flow valve (outsidediameter of the hollow portion) used for this wine bottle was 10 to 12mm. Specifically, when the inside diameter of the bottle opening inwhich the down-flow valve is press-fitted was reduced, the flow-downstagnation occurred. Then, when the down-flow valve 111 having the samestructure and dimension as the above-described structure and dimensionwas used, it became possible to effectively prevent the stagnation ofthe fluid flowing down from the down-flow hole 117 of the abutted piece119. Though specific causal relationship is not clear, it has been foundout that the use of the down-flow valve 111 can prevent such stagnationof the fluid.

The coil spring 115 in the hollow portion 112 is so structured that oneend thereof abuts on the discharge valve 114 and the other end abuts ona support piece 116 protruding into the hollow portion 112, respectively(refer to FIGS. 10 to 12). The support piece 116 is formed in a V shapeextending in a radial direction from the center of the hollow portion112 as shown in FIG. 12. The length of the coil spring 115 is set alittle longer than the distance between the discharge valve 114 and thesupport piece 116, so that the coil spring 115 sandwiched by thedischarge valve 114 and the support piece 116 is contracted. Further,since the support piece 116 abuts on the coil spring 115 only at a partof an end portion outer periphery thereof, the coil spring 115 as aresult is put into an inclined posture, and the center axis thereofbecomes to be nonlinear (refer to FIG. 10). Consequently, the pressuregiven to the abutted piece 119 via the discharge valve 114 becomesuneven on the periphery of the down-flow hole 117. This imbalanced loadcan be thought to be contributing to the prevention of the fluidstagnation. It has been experimentally confirmed that the prevention ofthe fluid stagnation can be realized with higher reliability byco-utilizing the imbalance caused by the coil spring 115.

(Concrete Structure of Fluid Extracting Device)

Next, the structure of the fluid extracting device will be explained indetail. The structure of the fluid extracting device in appearance waspreviously explained using FIGS. 1 and 3, and therefore, the internalstructure thereof will be mainly explained here with reference to FIGS.4 and 5. FIG. 4 shows the entire structure of the fluid extractingdevice 60 and FIG. 5 mainly shows in an enlarged state a portion of theextracting portion 67 to be described later. As shown in FIG. 4, thisdrawing shows the state when the fluid extracting device 60 is attachedto the bottle head portion B1 via the coupling assist 90 and they areset with the bottle being placed upside down. The down-flow valve 7being a plug with valve is press-fitted into the bottle head portion B1.

The fluid extracting device 60 includes the device body 61, theextracting portion 67, the operation mechanism 70, and other constituentelements. Both the fluid extracting device 60 and the bottle B are fixedby screw-connection with the coupling nut 91 of the coupling assist 90.However, if sufficient airtight is obtained between the cap 7 c of thebottle B and the device body 61 without utilizing the coupling assist90, the coupling assist 90 may be omitted.

The device body 61, which has a function as an airtight storagecontainer, is constituted of a connected structure of the mountingportion 63 and the fluid storage portion 65 that is coupled to a lowerportion thereof. The mounting portion 63 is constituted of the tubularportion 62 having the male thread portion on the outer peripheralportion thereof and the body portion 64 provided under the cylinderportion 62, both being integrally formed. The gas supply port 81, theair vent valve 83, and so on are provided in the body portion 64. Thegas passage 64 a (refer to FIG. 8) communicating with the gas supplyport 81 is formed in the body portion 64. The air vent valve 83 allowsair to be discharged therefrom when air inside the device body isinitially replaced with the N gas, and also serves as a safety valvewhen the pressure inside the device body 61 becomes excessively highwhile the extracting device is in use after being set. Further, the airvent operation can also be conducted by pushing and opening an escapevalve (not shown). However, the escape valve is not indispensable andmay be omitted in a case when the pressure inside the device body 61 isnot very high, a case when safety is ensured by other means, and thelike. An upper half portion of the inside of the mounting portion 63 hasa structure capable of housing a part of the head portion of the bottleB and a part of the down-flow valve 7.

(Structure of Fluid Storage Portion)

The fluid storage portion 65 formed in a circular container shape isprovided under a lower portion of the body portion 64. It is preferablethat the fluid storage portion 65 is made of a transparent material or atranslucent material and the surface thereof has calibrations 65 m forthe indication of an amount of the stored fluid (refer to FIG. 3). Thefluid storage portion 65 is connected and fixed to the lower portion ofthe body portion 64 via a flange portion 65 a formed near an upper edgeof the fluid storage portion 65 and a mounting ring 65 b. In passing,the lower portion of the body portion 64 and the mounting ring 65 b arecoupled to each other by screw fixing, but an O-ring 8 as s packing isdisposed between them, so that the airtight state of a joint between thebody portion and the fluid storage portion 65 can be maintained.

Further, an outer peripheral portion of the fluid storage portion 65 isconstituted of an upper portion corresponding to a portion serving as astorage chamber and a lower portion corresponding to a portion servingas a coupling portion, and the portion serving as the coupling portionis further formed in two steps, which are a large-diameter portion on anupper step and a small-diameter portion on a lower step. A male threadportion for attaching the later-described extracting portion 67 theretois provided on an upper cylinder portion 65 c on the upper step, and ina joining lower cylinder portion 65 d, on the lower step, a femalethread portion for attaching a later-described guide cylinder 68 theretois provided on an inner peripheral portion. Further, in a range from anupper end portion of an inner peripheral portion of the fluid storageportion 65 to a predetermined depth position, a step is formed so as tomake the inside diameter larger, and a rod guide 65 e supporting anupper portion of the later-described driving rod 75 is fitted therein.This rod guide 65 e acts through a guide hole provided at the centerthereof so as to allow an upper end portion (first driving portion) 75 gof the driving rod 75 to accurately press the discharge valve 7 b of thedown-flow valve 7. The fluid storage portion 65 is formed in a containershape, and an inner bottom portion thereof is formed in a truncated coneshape having gentle inclination angle, and a down-flow hole portion 65 ffor allowing the fluid stored in the fluid storage portion to flow downto the extracting portion 67 disposed downward is provided at a centerportion of the inner bottom portion.

(Structure of Extracting Portion)

The extracting portion 67 constituted of a cylindrical body having atapered external appearance is coupled to the lower portion of the fluidstorage portion 65. The extracting portion 67 is fixed in such a mannerthat an upper inner peripheral portion of an outer cylinder 67 a isscrew-connected to the lower cylinder portion 65 d positioned in thelower portion of the fluid storage portion 65. An inner cylinder 67 b isfitted in an inner peripheral face of the outer cylinder 67 a, and theinner cylinder 67 b is supported on a step formed at a lower end of theouter cylinder 67 a. An upper end portion is disposed so as to be incontact with a lower face of the step of the large-diameter portion ofthe fluid storage portion 65.

The extracting portion 67 includes the operation mechanism 70, whichenables the extraction of the fluid stored in the fluid storage portion65 under the airtight state. As shown in FIG. 5, a wide protrudingportion 67 e is formed in an intermediate height portion of an innerperipheral portion of the inner cylinder 67 b. The guide cylinder 68constituted of a bottomed cylindrical member with an opening portionthereof facing downward is coupled and fixed to the center of the insideof the extracting portion 67 in such a manner that an upper outerperipheral portion is screw-connected to an inner peripheral portion ofthe lower cylinder portion 65 d. The O-ring 8 as an airtight maintainingmeans is disposed between the lower portion of the fluid storage portion65 and the guide cylinder 68, so that the fluid or the N gas isprevented from leaking outside.

An up and down movement member 73 in a container shape constituted of abottomed cylindrical member is fitted to be able to move upward anddownward to an outer peripheral portion, which is a substantially lowerhalf of the outer peripheral portion, of the guide cylinder 68. The upand down movement member 73 is so structured that two lines offlange-shaped projecting portions 73 b are provided at a predeterminedinterval on an outer periphery upper end portion thereof, resulting inthe formation of a groove 73 a between the projecting portions, and ahole portion 73 c to which the extraction pipe 74 is able to insert isprovided at a lower end center portion thereof. Outer peripheralportions of two lines of the projecting portions 73 b are in contactwith an inner peripheral portion of the wide protruding portion 67 eformed in the middle of the inner peripheral portion of the innercylinder 67 b, and are able to slide relatively to the inner peripheralportion of the wide protruding portion 67 e. An upper convex ring 67 hand a lower convex ring 67 g are provided above and below the wideprotruding portion 67 e respectively, and protruding portions formed oninner peripheral portions thereof abut on upper and lower faces of theaforesaid two projecting portions respectively. The lower convex ring 67g provided below the projecting portions 73 b is biased upward by alower compression spring 67 i. The upper convex ring 67 h provided abovethe projecting portions 73 b is biased downward by an upper compressionspring 67 j. These two compression springs have the same spring constantso as to constantly keep the up and down movement member 73 positionedin a balanced state.

As shown in FIG. 4, the driving rod 75 including the first drivingportion for driving the down-flow valve (substitute stopper) 7 and thesecond driving portion for driving the extraction valve is providedupright in a range from the inside of the fluid storage portion 65 tothe lower portion of the extracting portion 67. The driving rod 75 is sostructured that a portion thereof positioned in the fluid storageportion 65 is constituted of a small-diameter portion 75 a, anintermediate-diameter portion 75 b, and a large-diameter portion(large-diameter rod portion) 75 c. The small-diameter portion 75 aenters into the hole portion of the rod guide 65 e provided in the upperportion of the fluid storage portion 65. The upper end portion 75 g ofthe small-diameter portion 75 a of the driving rod 75 serves as thefirst driving portion. When the driving rod is moved upward, guided bythe rod guide 65 e, it pushes up the discharge valve 7 b of thedown-flow valve 7, so that the valve can be opened.

As shown in FIG. 5, the extraction valve 71 is constituted of thelarge-diameter portion (second driving portion) 75 c of the driving rod75, the down-flow hole portion 65 f, and the O-ring 8 serving as apacking. When the large-diameter portion 75 c of the driving rod 75 isin a neutral state or at a position higher than this state, it isinserted into the down-flow hole portion 65 f provided in the lowerportion of the fluid storage portion 65, so that the fluid in the fluidstorage portion 65 cannot flow down. On the other hand, when the drivingrod 75 moves downward from the position, the large-diameter portion 75 cbecomes apart from the down-flow hole portion 65 f, resulting in an openstate of the hole portion, so that the fluid in the fluid storageportion can flow down into the guide cylinder 68 therefrom. Of course,since the first driving portion 75 g (refer to FIG. 4) is in a loweredstate at this time, the discharge valve 7 b of the down-flow valve 7 isin a closed state due to the biasing force of the bias spring. Since theO-ring 8 is provided at the down-flow hole portion 65 f, the inside ofthe fluid storage portion 65 and the inside of the extracting portion 67are kept airtight while the large-diameter portion 75 c is positionedhere.

A lower half portion of the driving rod 75, that is, a portionpositioned in the extracting portion 67, is substantially the extensionof the large-diameter portion 75 c to be an introducing portion 75 d ina cylindrical shape having an extraction hole therein. Four introducingholes 75 i (only one hole is shown) directed toward the center areprovided in a cylinder portion of the introducing portion 75 d, so thatthe fluid introduced into the guide cylinder 68 can be introduced to theextraction hole provided inside. A joint member 75 e fitted in a lowerinner peripheral portion of the guide cylinder 68 is coupled to a lowerend portion of the introducing portion 75 d integrally with the guidecylinder 68. The O-ring 8 as an airtight maintaining means is disposedbetween an outer peripheral portion of this joint member 75 e and aninner peripheral portion of the guide cylinder 68, thereby maintainingthe airtight state and preventing the fluid entering the guide cylinderfrom dropping.

The extraction pipe 74 is connected to a lower portion of the jointmember 75 e. The extraction pipe 74 is made of a tubular member sostructured that the outside diameter of an upper portion thereof is madeslightly larger than the outside diameter of a lower portion thereof,and a fluid outflow port 74 a is provided therein so as to verticallypass through. Further, the extraction pipe 74 is connected to the jointmember 75 e in such a manner that a male thread portion provided on anupper outer peripheral portion of the extraction pipe 74 and a femalethread portion provided on a hole portion of the joint member arescrew-connected. Further, a lower face of a bottom portion formed in alower end portion of the up and down movement member 73 is restrained bya collar portion 74 b formed on an outer peripheral portion of theextraction pipe 74, and an upper face thereof is restrained by a lowerend portion of the joint member 75 e. Accordingly, by means of theoperation of the operation mechanism 70, the up and down movement member73, the extraction pipe 74, the driving rod 75, the joint member 75 e,and so on are able to move upward and downward as one unit.

The operation arm 72 constituting the operation mechanism 70 is attachedto an intermediate height portion of the extracting portion 67. As shownin FIGS. 3 and 6, the operation arm 72 is so formed that both arms of anarm portion 72 a in a bifurcated shape embrace the outer cylinder 67 a,and a tip portion thereof is supported via fulcrum pins 70 c to amounting projecting portion 67 h provided so as to project from an outerperipheral portion of the outer cylinder 67 a. Swing pins 72 d areinserted into the respective arm portions 72 a at intermediate positionsof the length thereof. The swing pin 72 d has a male thread portion on aportion under a neck of a faced head portion, and a straight portionahead thereof. The portion being the male thread portion of the swingpin 72 d is screwed toward the inside from a side portion of the armportion 72 a, and the straight portion passes through arc-shaped grooves67 m (refer to FIGS. 1 and 3), which are provided in the outer cylinder67 a and the inner cylinder 67 b, to reach the groove 73 a of the up anddown movement member 73 (refer to FIG. 6). Therefore, the up and downmovement member 73 can move upward and downward by means of the swingpins 72 d when the arm portion 72 a is swung, thereby allowing thedriving rod 75, the extraction pipe 74, and so on to move upward anddownward. Incidentally, as the driving rod 75, the one that is formed asa single member is explained in this embodiment, but, with the adoptionof, for example, a driving rod that itself has a dual pipe structure,the up and down movement operation can be conducted separately for thedown-flow valve and the extraction valve.

(Method of Operating Fluid Extracting Device)

Next, the operation of the fluid extracting device will be explained.Under the state in which the fluid extracting device 60 is mounted on asetting table or the like as shown in FIGS. 3 to 5, the fluid in thebottle B cannot flow down since the discharge valve 7 b of the down-flowvalve 7 is closed. The operation of the fluid extracting deviceincludes, firstly, a work of replacing air in the device body 61 withthe N gas. This operation is performed by opening the air vent valve 83while supplying the N gas from the gas supply port 81 (refer to FIG. 1)and keeping this state for several seconds. When the air vent valve 83is closed thereafter, the inside of the fluid storage portion 65 isbrought into the state filled with the N gas.

Next, when a free end side of the arm portion 72 a of the operation arm72 is lifted, the tip portion of the driving rod 75 pushes up thedischarge valve 7 b of the down-flow valve 7, so that the fluid in thebottle flows down into the fluid storage portion 65. Also in this state,the large-diameter portion 75 c of the driving rod 75 as the extractionvalve is fitted in the down-flow hole portion 65 f in the lower portionof the fluid storage portion 65 to produce a closed state under thestate in which airtight is maintained via the mechanism of theextracting portion 67. Therefore, the fluid flowing down into the fluidstorage portion 65 does not flow down from the extraction valve to theextracting portion 67. Thus, the fluid in the bottle keeps flowing downwhile the operation arm 72 is kept lifted, so that the fluid in thefluid storage portion 65 keeps increasing until the fluid storageportion 65 is fully filled. If the N gas is continuously supplied alsoduring the operation, the N gas small in specific gravity goes up fromthe inside of the fluid storage portion 65 in place of the fluid to fillthe space produced in the bottle by the flow-down of the fluid, so thatthere remains no room in the bottle for air to enter.

Next, the flow-down operation of the fluid is continued under theeye-observation of the calibrations 65 m (refer to FIG. 3) of the fluidstorage portion 65, and when the operation arm 72 is returned to theneutral position at an instant when the fluid reaches a predeterminedamount, the first driving portion 75 g moves downward, so that thedischarge valve 7 b of the down-flow valve is brought into close contactwith the seat hole 7 i due to the biasing force of the compressionspring 7 d to stop the flow-down of the fluid (refer to FIG. 2 a). Alsoat this time, the N gas is similarly filled in place of the fluid in thespace which is made after the discharge of the fluid, and therefore, nodeterioration of fluid quality occurs since only the fluid and the N gasexist in the bottle, even when the discharge valve 7 b is closed.Incidentally, as for setting of the bottle, the upright setting is notindispensable as long as it is so inclined to allow the inside fluid tonaturally flow.

Next, when the arm portion 72 a of the operation arm 72 is pushed down,the large-diameter portion 75 c of the driving rod 75 is made apart fromthe down-flow hole portion 65 f of the fluid storage portion 65 by theoperation mechanism 70 as shown by the two-dot chain line in FIG. 5, sothat the fluid stored in the fluid storage portion flows down into theguide cylinder 68 through this down-flow hole portion. The fluid flowingdown into the guide cylinder 68 is further led to the inside of theintroducing portion 75 d having the extraction hole therein and flowsinto the extraction hole from the introduction hole 75 i provided in thecylinder portion of the introducing portion. Then, the fluid which haspassed through the extraction hole further passes through the inside ofthe joint member 75 e to be extracted to the outside through the fluidoutflow hole 74 a of the extraction pipe 74. At this time, the fluid iseasily poured to a glass or the like since a lower portion 73 f of theup and down movement member 73 protrudes downward from a lower endportion of the outer cylinder 67 a as shown by the two-dot chain line.Incidentally, the extraction of the fluid from the extraction pipe 74 iscontinued under this state, but when the arm portion 72 a is returned tothe neutral position at the completion of the discharge of the wholefluid in the fluid storage portion 65, the elements which have beenmoved downward by the operation mechanism 70 return to the neutralposition. When the fluid such as wine is to be extracted again next,wine or the like kept fresh can be extracted anytime by a similaroperation of the operation mechanism.

The foregoing explanation was made on the premise that the fluid is wineand the deterioration preventive gas is a gas mainly composed ofnitrogen (the N gas). But, as the deterioration preventive gas, othergases such as a carbon dioxide gas, a mixed gas of a nitrogen gas and acarbon dioxide gas, and other gases are adoptable. For example, in thecase of a carbonated beverage, the adoption of a carbon dioxide gas asthe deterioration preventive gas enables, in addition to the preventionof fluid deterioration, the prevention of loss of a carbonic acidcomponent. Further, the fluid may be other beverages such as whiskey,brandy, a carbonated beverage, a nutritional supplement, a dairyproduct, fruit juice with pulp, condensed fluid, fluid high in fluiddrag, and so on. But, needless to say, the selection of thedeterioration preventive gas is different depending on the nature of thefluid, and in addition, the fluid extracting device needs to have thestructure adaptable thereto.

As for the posture of the bottle to which the fluid extracting device isattached, it is generally set upright as shown hitherto in the drawings,but the bottle may be set, for example, in a tilted posture so as tomake a label or the like of the bottle impressive as shown in FIG. 7.Specifically, such a structure may be adopted that the length of acylinder portion 162 of a mounting portion of a fluid extracting device160 is made long and is constituted of a flexible member, and a bottleis coupled to a tip portion thereof via a coupling assist 190. In FIG.7, the structure of the fluid extracting device 160 is similar to thatof the fluid extracting device 60, but since the above-describedstructure of the first driving portion for driving the down-flow valveis incompatible, a flexible rod is adopted or a mechanism driven by adifferent operation from that of the second driving operation isadopted. In passing, the same reference numerals and symbols as those inFIG. 1 are used for other structures in the drawing.

(Modification Example of Fluid Storage Portion)

(Structure of Automatic Quantifying Device of Fluid Storage Portion)

Next, as for the fluid storage portion 65, the explanation in theabove-described embodiment was made on the fluid storage portion 65formed as the transparent material or the translucent material andhaving on the container-shaped surface thereof the calibrations 65 m forthe indication of an amount of the stored fluid, but in thismodification example, an automatic quantifying device structured to becapable of automatically supplying a fixed amount of a fluid as shown inFIG. 8 will be explained instead of the graduated fluid storage portion65. In passing, those denoted by the same reference numerals and symbolsas those in the above-described embodiment mean that they are the samemembers as those of the embodiment.

As shown in FIG. 8, an automatic quantifying device 66 is disposed in anupper portion of the fluid storage portion 65, and the body portion 64is disposed on an upper portion of the automatic quantifying device 66via a gasket 66. The automatic quantifying device 66 is constituted of arod bearing body 66 a having an inner bearing 66 b, a ring-shapedprojecting portion 66 c, a gas supply passage 66 d, an inside diameterportion 66 e, and rib portions 66 f. The inner bearing 66 b and theinside diameter portion 66 e are integrally connected by the ribs 66 fformed in radial, and passages are formed between the inside diameterportion 66 e and the inner bearing 66 b connected to each other by theribs 66 f Therefore, the inside diameter portion 66 e is formed in orderto constitute down-flow passages that allow the fluid such as wine toflow down from the bottle to the fluid storage portion 65. The insidediameter portion 66 e constituting the down-flow passages is isolatedfrom the gas passage 64 a formed in the body portion 64, so that the gaspassage 64 a formed in the body portion 64 is shielded by the rodbearing body 66 a. In this structure, the N gas is supplied to theinside diameter portion 66 e constituting the down-flow passages and tothe fluid storage portion 65 via the gas supply passage 66 d from theinside of the body portion 64. Further, an orifice is disposed in thegas supply passage 66 d. As for the gas supply passage 66 d, the gassupply passage 66 d itself may be formed as an orifice hole without theorifice disposed therein so that the gas supply passage 66 d is providedto have a throttle effect to the supplied gas. In this case, thedisposition of the orifice can be omitted.

The rod bearing body 66 a bears the driving rod 75 by the inner bearing66 b. The inside diameter portion 66 e constituting the fluid passagesfrom the bottle B is formed on a center side of the rod bearing body 66a, and on an inner side of the inside diameter portion 66 e, the innerbearing 66 b connected thereto by the ribs 66 f formed in radial isprovided integrally. The inner bearing 66 b of the rod bearing body 66 abears to be able to slide the small diameter portion 75 a of the drivingrod 75. The ring-shaped projecting portion 66 c formed by the extensionof the inside diameter portion 66 e is provided on a lower face of therod bearing body 66 a. In passing, the rod bearing body 66 a has afunction as a partitioning cover for shielding between the fluid storageportion 65 side and the body portion 64 side to which the down-flowvalve 7 for the bottle B is attached. Therefore, it is different fromthe rod guide 65 e shown in FIG. 4 explained in the aforementionedembodiment in that the rod bearing body 66 a has such a shieldingfunction. In other words, since the rod guide 65 e is intended forbearing to be able to slide the small-diameter portion 75 a of thedriving rod 75, the interval of a gap between the body and the bearingportion connected to each other by ribs of the rod guide 65 e is formedto be large. Therefore, when the fluid such as wine flows down to thefluid storage portion 65 via the down-flow valve 7 in the bottle B, thefluid sometimes scatters across the gap of the rod guide 65 e tocontaminate the inside of the body portion 64 of the device body 61. Inorder to remove the contamination, it is often necessary to detach thefluid storage portion 65 and the rod guide 65 e from the device body 61to wash the inside of the device body 61, but the rod bearing body 66 ahaving the shielding structure prevents the scattering into the bodyportion 64, which provides an advantage of eliminating the trouble offrequent washing or the like.

The orifice or orifice hole 66 d is intended for giving a drag to thegas pressure by throttling a flow amount supplied through the orifice ororifice hole 66 d at the time of supplying the N gas into the fluidstorage portion 65 from the gas passage 64 a formed in the body portion64 of the fluid extracting device 60, thereby making the discharge ofwine or the like slow at the end of the discharge in order to preventsuch a situation that the gas pressure blows out to cause the scatteringof wine or the like in splash at the end of the discharge of the fluidsuch as wine, the scattering being caused if the fluid such as wine isdischarged at a time when it is discharged from the fluid storageportion 65 to the extraction pipe 74. In passing, a filter is attachedto a tip of the extraction pipe 74 in FIG. 8 and the filter is a cap forremoving dregs of wine or the like.

In the automatic quantifying device 66, when the storage level of thefluid storage portion 65 is raised by the flow-down of the fluid fromthe bottle B to reach the ring-shaped projecting portion 66 c, anopening of the ring-shaped projecting portion 66 c is closed by thefluid to automatically stop the flow-down of the fluid from the bottleB. This is because the N gas in the fluid storage portion 65 cannotenter the ring-shaped projecting portion 66 c by the closing of theopening, so that it does not reach the inside of the bottle B.Specifically, when the fluid flows down from the bottle B, the pressureinside the bottle B lowers by a corresponding amount, and the flow-downof the fluid is continued when the N gas, if it enters, compensates thereduction amount of the pressure, but since the N gas cannot enter, theflow-down of the fluid is stopped.

Therefore, as for the flow-down of the fluid, when the free end side ofthe arm portion 72 a of the operation mechanism 70 is lifted (refer toFIG. 5), the discharge valve 7 b of the down-flow valve 7 opens to causethe fluid in the bottle B to flow down into the fluid storage portion65, but when the fluid flowing down reaches the opening of thering-shaped projecting portion 66 c, an amount of the fluid is fixed inthe fluid storage portion 65 even if the operation arm is kept lifted,so that the flow-down is automatically stopped. This eliminates thetrouble of operating the operation arm under the monitoring of theflow-down motion of the fluid by an eye-observation of the calibrations65 m of the fluid storage portion 65 (refer to FIG. 3).

(Structure of Mounting Fluid Extracting Device on Display Table or theLike)

In FIG. 8, a bottle holder 200 in relation to the fluid extractingdevice 60 is shown by a virtual line. The bottle holder 200 is composedof a tubular portion 201 in a cylindrical shape and a bottom portion 202in which an insertion hole is formed at the bottom center thereof. Thecylinder portion 62 of the body portion 64 of the fluid extractingdevice 60 is inserted into the insertion hole of the bottom portion 202and is, for example, screwed to the insertion hole to be fixed to thebottom portion 202.

In order to realize the connection of the body portion 64 to the bottomportion 202 of the bottle holder 200, the opening portion of the bottomportion 202 is so formed to allow the body portion 64 to be directlyscrewed thereto. With such a structure that the body portion 64 is thusdirectly connected to the bottom portion 202 of the bottle holder 200,it is possible to detach the fluid storage portion 65 by releasing thescrew connection of the mounting portion 63, which facilitates washingand so on to enable good sanitary control. The bottle of wine or thelike is inserted to the bottle holder 200 in the upside down state withthe opening portion thereof facing downward and is kept upright.Incidentally, the tubular portion 201 of the bottle holder 200 is notlimited to that in a cylindrical shape but may be, for example, in arectangular shape.

An upper portion of the bottle holder 200 is fixed to a table plate 301of a display table such as a wagon by an appropriate fixing means. Inthe drawing, the installation state with one fluid extracting device 60is shown for the convenience of explanation, but the fluid extractingdevices 60 may be arranged in plurality or in a plurality of lines onthe table plate 301.

(Clamp Structure)

Explanation will be given based on FIGS. 14 to 16. A clamp structure 250is intended for preventing the bottle attached to the fluid extractingdevice from coming off. The clamp structure is not an indispensableelement, but when a relatively large bottle is held or when a bottlehaving a head in a peculiar shape is held, it is advantageous to providethe clamp structure for more stable support.

The basic portion of the clamp structure 250 is composed of a ring 252capable of rotating in a circumferential direction relative to thetubular portion 201 of the bottle holder 200, and a fixing plate 254provided to be able to slide relative to an inner peripheral face of thering 252. A pair of cam plates 255 in a shape similar to a baseball homebase are provided on the ring 252, and a pair of clamp arms 257substantially in an S shape each pivotally supported by a pivotal shaft256 at one end and being open at the other end are provided on thefixing plate 254. A lock piece 258 capable of engaging with a lock pin259 protruding onto the ring 252 is provided at a terminal on one endside of each of the clamp arms 257. By this engaging, both of the clamparms 257 are kept in an open state with a predetermined interval betweenthem so as to allow the bottle head portion to insert therein. A gripmember 261 as a slip stopper is provided on a bottle side of each of theclamp arms 257.

Here, when the bottle head portion is inserted between both of the clamparms 257 and attached to the fluid extracting device, the ring 252 isrotated clockwise. The cam plates 255 also rotate in accordance with therotation of the ring 252. The rotating cam plates 255 are brought intocontact with end faces of the clamp arms 257 to turn the clamp arms 257in a clamp direction by a cam action. When the pair of clamp arms 257turn in the clamp direction respectively, the distance between them isnarrowed to firmly clamp the bottle head portion. A gripping effect ofthe grip member 261 further ensures the clamping. Finally, when a screw253 is fastened to fix the ring 252 so as to prevent the ring 252 fromrotating, the clamping work is finished. The clamp can be released by awork through the reverse procedure to the procedure described above. Theprevention of the bottle from coming off by the clamp structure 250prevents air from entering the fluid extracting device and the bottledue to the coming off, resulting in the effective prevention of thedeterioration of the fluid to be extracted.

(Bottle Centering Device)

As shown in FIG. 8, a centering device 400 for keeping the bottle B inan upright state is provided for each of the bottle holders 200 on thetable plate 301. The centering device 400 is so structured that aplurality of posts 401 are provided to stand on the table plate 301,springs 402 are hung at, for example, three places of the periphery asshown in the drawing, and the bottle B is kept upright, being placedupside down relative to the bottle holder 200. For example, as shown inFIG. 18, each of the springs 402 includes such a structure that a longcylindrical member 403 a and short cylindrical members 403 b, 403 b,which are made of a soft material such as synthetic rubber or syntheticresin and arranged in a tripartite state in an axial direction, areloosely fitted to the spring 402 so as to be able to rotate. In passing,the centering device 400 is not limited to this form, but such acentering device or the like is also included that, for example, a linkmechanism including rollers is elastically brought into contact with abottle.

The use of the bottle holder 200 and the centering device 400 installedon the display table as described above makes it possible to attach thebottle B of wine or the like to the fluid extracting device 60 with asingle operation. Further, when the fluid extracting devices 60 are usedbeing mounted on the table plate of a wine display table or the like,for example, when they are applied to a bottle setting table or the likeat a wine bar or the like, an aesthetic appearance is provided to theeyes of customers, and on the working staff side, operability in pouringwine to a glass or the like is good and handling of bottles isfacilitated. Further, when a wine display table or the like on whichthese fluid extracting devices 60 are installed is used on a wagon-typecarrier or the like with casters for the display table, it can be movedfreely on the floor for serving, which greatly enhances availability.

(Structure of Display Table)

FIG. 17 is a schematic explanatory view showing the arrangementstructure when box cells housing the fluid extracting devices areattached to the display table and a deterioration preventive gas supplyunit is connected thereto. FIG. 18 is a schematic plane viewschematically showing the arrangement relationship structure in a planarsee-through state, in which parts of the box cells, the fluid extractingdevices, and so on are left and other portions are omitted. FIG. 19 isan explanatory view showing the rear state of the arrangement structurein which the box cells housing the fluid extracting devices are attachedto a display table. As shown in FIGS. 17 to 19, a display table 300includes such a structure that an upper frame 302 on which a table plate301 is placed is disposed on a top portion, a prop frame 303 is providedextending downward from each of four corners of the upper frame 302, apartition frame 305 on which a partition plate 304 is placed is disposedin a middle portion, and a bottom frame 307 on which a bottom plate 306is placed is disposed on a bottom portion. Legs 308 with casters areappropriately provided at lower ends of the prop frames 303 or at lowerface of four corners of the bottom frame 307. A deterioration preventivegas supply unit 700 for feeding the N gas to the fluid extracting device60 for each of the bottles B is disposed on the bottom plate 306 of thedisplay table 300.

The deterioration preventive gas supply unit 700 includes a gas bomb 701set on the bottom plate 306, and a pipe 702 connecting between the gasbomb 701 and the gas supply ports 81 of the fluid extracting devices 60.As shown in FIG. 17, the pipe 702 is disposed closer to a customer side(left side in the drawing) so as not to obstruct the servicing operationat hand on the working staff side. In a pipe passage connected to adownstream side from an outlet gas cork of the gas bomb 701, provided isa pressure control device in which a first change-over valve used at thetime of bomb replacement, a first pressure gauge, a filter for removingimpurities such as dust and dirt, a pressure regulator for adjusting thepressure at an actually used value, a filter for removing gas smell, asecond change-over valve used at the time of cleaning the filter forremoving gas smell, and a second digital pressure gauge and an analogpressure gauge for fine adjustment of the adjusted pressure are arrangedin sequence, though reference numerals and symbols of these componentsare omitted in the drawings. A pipe passage on a further downstream sideis inserted to the partition plate 304 to extend along the partitionframe 305. The pipe 702 above the partition plate 304 branches off toindividual nozzles, which are connected to the gas supply ports 81 ofthe respective fluid extracting devices 60, so that the N gas is fedthereto. In FIGS. 18 and 19, gas tubes though which the N gas is sent tothe respective gas supply ports 81 from the pipe 702 are omitted. Thepressure control device such as the pressure regulator is structured tobe controlled by a controller. Control devices such as the controllerare appropriately disposed in a not-shown control box installed on thebottom plate 306 of the display table. In passing, a gas supply sourceof the deterioration preventive gas supply unit 700 is not limited tothe one having the gas bomb 701 mounted thereon explained here, but adifferent gas producing device may be mounted on the display table suchas a wagon or the like. Alternatively, as such a type mounted on thedisplay-table, such a gas supply structure may be adopted that a gasbomb or a gas producing device as a different gas supply structure isinstalled outside the display table such as a wagon, this is connectedto a gas tank placed on the display table by a gas tube or the like, andwhen an amount of gas in the gas tank becomes small, a new supply of theN gas is made from the gas bomb or the gas producing device outside thedisplay table.

(Regarding Display Table in Stepped Form)

As previously described, when the fluid extracting devices 60 areinstalled on a bottle setting table, a wine display table, or the likeat a wine bar or the like, the arrangement thereof in plurality or in aplurality of lines lengthwise and widthwise on the table plate of thedisplay table will result in flat arrangement, which is not attractiveto look at for a customer side from an aesthetic viewpoint, and at thesame time, problems such as inconvenience for a serving side in pouringto a glass may possibly occur.

In this embodiment, in order to cope with such problems, furtherimprovements and devices are made so as to form the display table in astepped form. As shown in FIG. 17, the structure with the steppedarrangement is such that the heights of the positions where the bottleholders 200 are attached to the table plate 301 are varied from oneanother, thereby enabling the stepped arrangement. FIG. 17 shows a statein which the table plate 301 of the display table having an upper end ofthe bottle holder 200 fixed thereto is arranged at the lowest positionto form a first step, as shown on the left side of the drawing. The nextsecond step on the right side thereof (center in FIG. 17) is formed insuch a manner that the table plate 301 having the shown bottle holder200 fixed thereto is fixed to a one-step higher intermediate portion ofa box cell 500, and further, a third step shown on the right side of thedrawing is formed in such a manner that the table plate 301 having thebottle holder 200 fixed thereto is fixed to the highest position of thebox cell 500, so that the height becomes larger in this order. Suchstructure allows bottles to be arranged widthwise and lengthwise and ina stepped form on the display table, which results in the arrangementwith the backward side being higher for customers, so that they caneasily recognize the brand and kind of each bottle of wine or the like,and which results in the arrangement with the forward side being higherfor working staff, so that they can easily pour wine or the like to aglass or the like from bottles, and therefore, this arrangementfacilitates the operation at hand and allows the working staff to easilyserve customers, for example, to wait on the customers (refer to FIG.19). The bottle B can be put into and out of the box cell 500 by openinga cover plate 502 that can be opened/closed freely as shown by animaginary line in FIG. 17. This cover plate 502 is so structured that,when it is closed, it is held by, for example, an electromagnet or thelike fixed to an upper end of a wall portion 503.

(Regarding Structure of Cooling Device in Display Table or the Like)

In the application to bottle service at a wine bar or the like asdescribed above, what is important is, in addition to the prevention ofthe quality deterioration, cooling bottles to a proper optimumtemperature and maintaining and keeping this temperature. In thisembodiment, as shown in FIG. 17, the box cells 500 made of acryl or thelike are formed and these box cells 500 are placed on the top plate ofthe display table 300. Each of the box cells 500 is composed of wallportions 503, 503 provided along side peripheries, the cover plate 502provided at a top, and the table plate 301 provided at a bottom. Thebottle holders 200 are attached to the table plates 301 of the box cells500 at the intervals corresponding to those of the bottles, and thetable plates 301 to which the bottle holders 200 are attached are fixedto the wall portions 503 of the box cells 500, so that cooling chambersare constituted in respective spaces each defined by the box cell 500and the table plate 301. The height positions where the table plates 301are attached to the wall portions 503 are made different from oneanother so that level difference among the respective box cells 500 ismade in the bottom portions of the wall portion 503. The fluidextracting devices 60 are attached to the bottle holders 200, and thecentering devices 400 are provided on the table plates 301. To a topface of each of the box cells 500, the cover plate 502 similarlyconstituted of a transparent material such as acryl is attached by ahinge or the like so as to be freely opened and closed, and when thecover plate 502 is opened, it is possible to freely attach a bottle ofwine or the like to the bottle holder 200 and replace it with anotherone. Further, the table plates 301 can be arranged in a stepped form asdescribed above in such a manner that the heights of the positions wherethe box cells 500 are attached to the wall portions 503 are changedstepwise in a unit of each lengthwise line or widthwise line. Therefore,the wall portions 503 of the box cells 500 are so formed that theheights of the wall portions 503 are also changed stepwise in a unit ofeach line so as to form the cooling chambers in a stepped form. Inpassing, the box cells may be those, though not shown, formed to havehorizontal cross sections in a rectangular shape or a circular shape,and the shape thereof is not to be particularly limited. As isunderstood from the above explanation, the significance of disposing thebottle holders 200 is to set the positions where the fluid extractingdevices 60 are operated at positions where easy handling is possible insuch cases when the table plates 301 are arranged in a stepped form, andto eliminate the necessity of cooling the entire bottle since attachingthe bottle holders 200 to the table plates 301 reduces the volumecapacity of the cooling chambers where the bottles of wine or the likeare cooled, so that cooling efficiency is enhanced.

The structure of the cooling device will be explained based on FIG. 18.FIG. 18 is a schematic plane view where portions of the box cells, thefluid extracting devices, and the centering devices are left and otherportions are omitted in order to schematically explain a planarsee-through state of the structure of the arrangement relationship inwhich the cooling devices and so on are arranged on the display table300. The box cells 500 formed to be long sideways constituting thecooling chambers which are sealed spaces are placed in three lines onthe table plate 301 of the display table 300. A cooling device 600 isdisposed at the center of each of the box cells 500 which are longsideways, and a plurality of bottles of wine and so on, though notshown, are contained on both right and left sides thereof.

(Schematic Structure of Cooling Device)

The cooling device 600 is a cooling device using a thermoelectric moduleof a Peltier element. This cooling device keeps the inside of thecooling chamber, which is a sealed space of the box cell 500, at aconstant temperature by cooling air or a refrigerant to an appropriatetemperature. Cooling devices using the Peltier element have recentlybeen drawing attention as non-use fluorocarbon cooling devices from aviewpoint of the environmental protection of the earth. In acommonly-used cooling device using a compressor, the increase in size ofthe device itself is inevitable, and driving noises of the compressorare also unpleasant to ears at wine bars and so on, and therefore, it ispreferable to use the cooling device using the thermoelectric module ofthe Peltier element as the cooling device for bottles of wine and so on.The thermoelectric module is made of a member having two conductivefaces and having a function that when a direct current is passed, one ofthe conductive faces is heated and the other is cooled. Accordingly, oneof the faces functions as a generating surface or a heat radiatingsurface and the other face functions as a heat absorbing surface.

The schematic structure of the cooling device 600 of this embodiment issuch that it has a plurality of stages of disc-shaped thermoelectricmodules in which a large number of P-type semiconductors and N-typesemiconductors having a Peltier effect are connected in series, and asshown in FIG. 19, it has, on both sides of the table plate 301 of thebox cell 500 constituting the cooling chamber in which air as a heatmedium is filled in a sealing state, a heat absorbing portion 601disposed inside the cooling chamber of the box cell 500 and a heatradiating portion 602 disposed outside the cooling chamber, and itoperates such that heat absorbed in the heat absorbing surface isheat-exchanged to the heat radiating surface outside the box cell whilea not-shown stirring fan disposed to pass through the center portion ofthe thermoelectric modules is stirring air as the heat medium, and theheat is released to the atmosphere from the heat radiating portion 602by radiator fins provided outside the box cell and by a not-sown heatrelease fan, thereby cooling the inside of the cooling chamber.Incidentally, the cooling device 600 may be attached to the wall portion503 of the box cell 500. Convection deflection plates 504, 504 areprovided at a center portion of the cover plate 502 to form a downward Vshape and arranged so as to further promote an air stirring effect. FIG.19 shows the state in which temperature controllers for indicating thecooling temperatures inside the box cells 500 by the cooling devices 600are disposed, together with breakers, on a panel in a lower left of arear portion of the display table 300, and the pressure gauges, thechange-over valves, and so on of the pressure control device of thedeterioration preventive gas supply unit 700 are disposed in a lowerright of the rear portion of the same so as to be easily seen and easilyoperated by working staff.

In the cooling device 600 having the thermoelectric modules builttherein, it is possible to make fine temperature setting for temperatureadjustment by giving switch changeover function, and it is also possibleto adjust a cooling capability by varying the number of thesemiconductors constituting the thermoelectric modules on the respectivestages, so that temperature control can be conducted in such a mannerthat atmospheres at different optimum temperatures are formed dependingon producing areas, brands, and so on of wine or the like and delicatefine adjustment to the optimum temperature is made individually bottleby bottle.

In FIG. 18, one cooling device 600 is disposed in each of the box cells500 made of acryl or the like on each step of the table plates 301arranged in a three-stepped form in the wagon-type wine display table300, and each of the cooling chambers is kept to be airtightindividually. One cooling device 600 is placed horizontally at thecenter of each of the individual cooling chambers. In passing, the tableplates 301 are not limited to those in the stepped form shown in thedrawing but may be one piece of a flat-plate type table plate, and withsuch stepped-type table plates or flat-plate type table plate, a form inwhich one box cell and one cooling device are disposed for one bottlemay be adopted. When the form in which one box cell and one coolingdevice are disposed for one bottle is adopted, fine adjustment intemperature control can be made bottle by bottle according to thevariety and brand of wine or the like, so that it is possible to give aservice capable of providing quality and taste under the optimumtemperature control.

Further, the temperature control of the cooling devices 600 can bemonitored individually for each box cell through the indication bytemperature indicators, though not shown, which are installed for therespective box cells on front panels disposed on the partition frame 305and the bottom frame 307 of the display table 300. The temperaturecontrol of the cooling devices 600 is performed by a control device suchas the controller disposed in the not-shown control box installed on thebottom plate 306 of the display table.
